Fire Emblem: Hasha no Tsurugi

, lit. Fire Emblem: The Champion's Sword) is a Fire Emblem manga that depicts the adventures of Al, a young boy with a mysterious past. It is initially a side-story to Fire Emblem: The Binding Blade, but it becomes more of an alternate retelling of the game's story from Volume 3 onwards.

The manga is referenced in the actual game in the form of the items Al's Sword, Gant's Lance, and Tiena's Staff, named after the three main original characters introduced in this work. Some of the manga's original characters have since appeared in the card game Fire Emblem 0 (Cipher).

While the manga is a side story of Fire Emblem: The Binding Blade and most of the plot is accurate to the game, some of the story has been modified slightly in order to incorporate Al and a few other original characters. As a result of this, the later developments differ substantially from the events in the game; the series continues on for several more chapters devoted to Al's side of the story after Roy's triumph.

Several Plot holes can be seen that impacts Fire Emblem: The Binding Blade. Notable examples of plot changes include:

There is a Nintendo event with Fire Emblem: The Binding Blade that unlocks a Trial Map of that in similar to Tiena's rescue.

One of the volumes ends with a picture of some characters from FE7 such as Lyndis and Matthew.

Usually, at the end of each chapter where an important character is introduced, "personal data" statistics appear, but most of the information is usually off from the actual game's statistics. For instance, Niime is identified as a "Sage", while she is actually a "Druid".

Like the game, the manga has received a fan-based translation instead of an official translation.
